Does it work on all plastics?
Yes, it works on all exterior plastics and rubber, although if the plastic is faded it may show up underlying inconsistencies in finish (sometimes further application of product reduces patchiness).
How long does it last?
Usually several weeks to many months, depending on area of application, ambient conditions, car storage conditions and mileage driven. Tyres get dirty quickly so don't expect too much. But do a 50/50 on trim and you can often see a tangible 'applied vs non-applied' finish 9 months later!
Will it sling off onto paintwork?
No, once it's cured it stays put. Wet dressings are sticky and collect dirt. Not Taint it Black.
Does it leave a glossy or matt finish?
It leaves a natural matt finish on tyres when buffed (think matt black not dull brown) and a rich satin sheen on plastic trim and window rubbers (rather than full blown gloss).
Why reference Backstreet Boys in the description when Taint it Black is word play on a Rolling Stones song?
Good question, Pop Master! MrSkittles will get back to you. Maybe.
